Episodic Events and Trophic Pulses: Estimating Surface Chlorophyll and Sediment Concentrations Using Remotely Sensed Imagery
^{An edge detection algorithm to detect the 4 degree C thermal bar
(maximum density boundary between near and off-shore waters) in AVHRR
satellite lake surface temperature images of the Great Lakes is
of great value for creating multispectral analysis products.
Images of this type show relationships that occur between different
physical parameters in the aquatic system that may have been collected
from different instruments.

This work focused on combining simultaneously acquired SeaWiFS
chlorophyll and turbidity maps with thermal front maps of southern Lake
Michigan during the spring. Strides made in the combination of
these instrument bands and the improvement of temporal and spatial
continuity through objective interpolation will be covered.
The continued development of advanced
data visualization tools will aid the understanding of the relationship
between physical and biological processes in the Great Lakes.}
